Nanoscale UV-absorber for sustainable paint and coating applications

Wessels W., Nolte U., Berkei M., BYK Chemie GmbH, DE

Innovative nanomaterials are finding their way into paints, coatings, and plastics applications. Beside improving or modifying the mechanical polymer properties, giving higher scratch resistance for example, nanoscale materials like CeO2 are applied to improve UV [...]

Use of Nanocrystalline Ceria in EUV Lithography Optics Polishing

Murray P.G., Böhm T., Maltor H., Nanophase Technologies Corporation, US

EUV lithography promises a huge gain in resolution due to the extremely short wavelength. The necessity of aspherical off-axis mirrors dramatically increased the challenge of manufacture compared to refractive designs. Due to the short wavelength [...]

Lattice Constant Dependence on Particle Size for Bulk and Doped Ceria prepared from a Citrate Sol-Gel

Morris M.A., Morris V.N., Farrell R.A., Sexton A.M., Morris M.A., Morris V.N., Analog Devices, Dimensional Solids Group, UCC, IE

High surface area ceria nanoparticles have been prepared using a citrate sol-gel precipitation method. Changes to the particle size have been made by calcining the ceria powders at different temperatures, and X-ray methods used to [...]

Nanocrystalline Mixed Metal Oxides Novel Oxygen Storage Materials

Sarkas H., Murray P.G., Fay A., Brotzman Jr. R.W., Nanophase Technologies Corporation, US

Nanophase Technologies Corporation employs a new physical vapor synthesis technique to manufacture ceria-based mixed rare earth oxide nanomaterials. The mixed rare earth oxide nanoparticles are dense, discrete crystals. The compositions are solid solutions that remain [...]
